Help! For over a month, on and off..... My leg will out of the blue feel achey, pins and needle feeling, and feels like the back of my leg has a crampy pulling like sensation????? It's freaking me out. No redness, no swelling..... No bruising...... I am starting to think this is the start of MS, or lupus, or fibro?.... Bad circulation????? It's causing me anxiety! I have been to docs and they possibly pinched a nerve????? But this has gone on for soooooo long! Shouldn't this be fixed by now?
